Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566496, here are decompositions:

23 + 31566473 = 31566496
47 + 31566449 = 31566496
53 + 31566443 = 31566496
107 + 31566389 = 31566496
113 + 31566383 = 31566496
149 + 31566347 = 31566496
167 + 31566329 = 31566496
179 + 31566317 = 31566496

Showing the first eight; more decompositions exist.
